Category: None Group: None >Status: Pending >Resolution: Invalid Priority: 5 Private: No Submitted By: Elio Blanca (eblanca76) Assigned to: Nobody/Anonymous (nobody) Summary: Bug in VBR quality value? Initial Comment: I've just built lame-3.99.3, I'm now performing a series of tests on an audio clip, just tweaking the encoding quality via the `-q' and the `-V' switches. Now in the resulting mp3, sometimes the quality factor doesn't change with the `-q' value! So, when encoding `-q 0 -V 5' the quality byte stores 50 and when I set `-q 1 -V 5' that byte is still 50. When encoding `-q 2 -V 5' the quality value is 50 as well and the same happens with `-q 3' and `-q 4'. This value changes for `-q 5', `-q 6' and `-q 7', then it remains 43 (the same as `-q 7') for `-q 8' and `-q 9', why? Is the same quality used under some circumstances? ---------------------------------------------------------------------- >Comment By: Robert Hegemann (robert) Date: 2011-12-30 01:36 Message: That's not a bug. ABR/VBR/CBR encoding modes have only a handful of possible q settings implemented. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=100290&aid=3466159&group_id=290 ------------------------------------------------------------------------------ Ridiculously easy VDI.
